More tricks for rapid calculation!

Suppose you an equation in the following format: (ax+b)/(cx+d)=p/q, you can solve for x with this formula:

x=(dp-bq)/(aq-cp)

Here's an example:

Fast Way

(2x+1)/(3x+2)=4/5

So let's set the values according to this format (ax+b)/(cx+d)=p/q for every variable

a=2, b=1, c=3, d=2, p=4 and q=5

Now let's fit the values into our formula x=(dp-bq)/(aq-cp)

x=((2)(4)-(1)(5))/((2)(5)-(3)(4))

x=(8-5)/(10-12)

x=-3/2

Normal Way:

(2x+1)/(3x+2)=4/5

Cross Multiply

4(3x+2)=5(2x+1)

12x+8=10x+5

2x=-3

x=-3/2
